EventHandler not triggering.

in Program.cs

namespace ClipboardHistoryCLI
{
    internal class Program
    {
        static void Main(string[] args)
        {
            ClipboardHandler handler = new ClipboardHandler();

            CommandParser parser = new CommandParser(args);
            string[] list;

            list = parser.ListComponents();
            Console.WriteLine($"{list} TEST");

            do
            {
                Console.WriteLine("HI");
                Thread.Sleep(1000);
            }
            while (true);
        }
    }
}

namespace ClipboardHistoryCLI
{
    internal class Program
    {
        static void Main(string[] args)
        {
            ClipboardHandler handler = new ClipboardHandler();

            CommandParser parser = new CommandParser(args);
            string[] list;

            list = parser.ListComponents();
            Console.WriteLine($"{list} TEST");

            do
            {
                Console.WriteLine("HI");
                Thread.Sleep(1000);
            }
            while (true);
        }
    }
}

in ClipboardHandler.cs:

namespace ClipboardHistoryCLI._Clipboard
{
    internal class ClipboardHandler
    {
        private Dictionary<string, DataPackageView> _clipboardHistory = [];

        public ClipboardHandler()
        {
            Clipboard.ContentChanged += new EventHandler<object>(this.ClipboardChanged);
        }

        private void ClipboardChanged(object? sender, object e)
        {
            Console.WriteLine("TEST");
            Console.WriteLine($"{sender}, {e}");
            Console.WriteLine($"{sender.GetType()}, {e.GetType()}");
        }

namespace ClipboardHistoryCLI._Clipboard
{
    internal class ClipboardHandler
    {
        private Dictionary<string, DataPackageView> _clipboardHistory = [];

        public ClipboardHandler()
        {
            Clipboard.ContentChanged += new EventHandler<object>(this.ClipboardChanged);
        }

        private void ClipboardChanged(object? sender, object e)
        {
            Console.WriteLine("TEST");
            Console.WriteLine($"{sender}, {e}");
            Console.WriteLine($"{sender.GetType()}, {e.GetType()}");
        }

Wrote a very basic setup to learn to work with an EventHandler. The event however does not trigger, I had wrapped Main into an async method, I made ClipboardChanged async, i added an async delay on the main keep-alive loop, nothing worked for me. Any idea why the EventHandler doesnt trigger? ClipboardChanged is an official UWP EventHandler: https://learn.microsoft.com/en-us/uwp/api/windows.applicationmodel.datatransfer.clipboard.contentchanged?view=winrt-22621
